On Grid Solar
The lowest cost per unit. Export surplus power to the grid and earn credits on your bill.
Why Choose Zolar for On Grid Solar
An on grid (grid tied) system works alongside your DISCOM connection. Solar power runs your loads first, and any surplus is exported through a net meter and adjusted against your bill. It is the most affordable and most popular configuration in India, and it is eligible for the PM Surya Ghar subsidy.
- Lowest Investment per kW
- Fastest Payback, Typically 3 to 5 Years
- Eligible for the PM Surya Ghar Central Subsidy
- Net Metering Credits for Every Surplus Unit
- Minimal Maintenance with No Batteries
- Works for Homes, Businesses and Factories
What's Included
Generation
Solar panels generate DC power during the day and the grid tie inverter converts it to AC.
Self Consumption
Your appliances use solar power first, so you buy fewer units from the grid.
Export
Surplus units flow to the grid through a net meter and earn credits on your bill.
Good to Know
For safety, the system shuts down during grid outages and needs DISCOM net metering approval.
Ideal for
“A solar plant is a 25 year promise. We engineer it like one.”

Everything you need to know about going solar: costs, subsidy, approvals and maintenance.
For homes, an on grid system typically costs ₹55,000 to ₹70,000 per kW before subsidy, depending on brand, structure height and site conditions. Commercial and industrial systems cost less per kW thanks to scale. Use our solar calculator for an instant estimate, then book a free site assessment for an exact quote.
Residential consumers get ₹30,000 per kW for the first 2 kW and ₹18,000 for the 3rd kW, up to ₹78,000 for systems of 3 kW and above. Special category states and UTs receive higher amounts. Housing societies can also claim support for common facilities. We file and track your subsidy end to end.
You need roughly 80 to 100 sq. ft of shadow free area per kW. A 5 kW home system needs about 400 to 500 sq. ft. Elevated structures let you keep using the terrace underneath.
Homes typically recover their investment in 3 to 5 years after subsidy, and commercial users in 3 to 4 years thanks to higher tariffs. With panels lasting 25+ years, you enjoy two decades of nearly free electricity.
No. For safety, on grid inverters shut down when the grid fails so no power flows back to linemen. If you need backup, choose a hybrid system with batteries, which keeps critical loads running automatically.
Tier 1 modules come with a 25 to 30 year performance warranty and typically degrade only ~0.5% a year. Inverters usually last 10 to 15 years.
